Catalytic combustion is used in those industries
I. Wood-based panel manufacturing and wood products furniture industry
Manufacture of wood-based panels: common ones are simple plywood hot-pressed plywood, decorative veneer or veneer
Manufacturing. The total VOCs generated in the above process mainly come from the coating and hot pressing processes. The main adhesives are urea formaldehyde, phenolic formaldehyde, and melamine resin.
The sources of total VOCs for wood product furniture manufacturing are mainly white latex, hot-melt adhesive, and painting processes.
Exhaust gas composition: mainly toluene, xylene, benzene, supplemented by other mixed thin materials
Printing industry
The printing industry can be divided into letterpress printing, lithography, gravure printing, and holes according to its production process
Printing.
Exhaust gas composition: mainly toluene, xylene, benzene, supplemented by other mixed thin materials
Third, the shoe industry
The process of producing organic waste gas in the shoe industry mainly includes 商标 upper trademark printing process, high frequency molding process of upper material, sole material EVA, MD foaming, sole spray painting process, sole midsole fitting, upper sole adhesive Molding process.
Exhaust gas composition: high density organic polymer, may contain chlorine and sulfur, trace amounts of triphenyl and esters
Third, car painting and car maintenance
Exhaust gas composition: toluene, xylene, acetone, acetic acid, butyl ester, acrylic paint, pure benzene
Fourth, spray paint industry
VOC exhaust gas types in the spray paint industry:
